   <abstract xml:lang="ru">
    <p>На основании известных теоретических представлений о фотобиохимической основе свечения клеток Noctiluca scintillans получена аналитическая формула расчета скорости экспоненциального спада интенсивности биолюминесценции. Формула получена для случая времен протекания процесса светоизлучения далекого от инициации вспышки, чтобы исключить влияние нелинейных процессов, в частности распространение потенциала действия в тонком периферическом слое цитоплазмы клетки Noctiluca scintillans . Полученная формула отражает дополнительную связь между параметрами модели свечения Noctiluca scintillans , которая позволяет исключить один из шести оптимизационных параметров при аппроксимации теоретической кривой вспышки к экспериментальным данным. Анализ полученной формулы позволяет сделать вывод о том, что в зависимости от физиологического состояния клетки скорость экспоненциального спада фотоэмиссии может меняться, т.е. для одной и той же клетки можно ожидать вспышки с несколько отличающимся фронтом спада. Такой вывод подтверждается данными проведенных ранее измерений.</p>

   <trans-abstract xml:lang="en">
    <p>An analytical equation for exponential bioluminescence decay rate calculation was obtained using photobiochemical background of the light emission of Noctiluca scintillans. The equation was derived for light emission times elapsing well after flash initiation in order to avoid an influence of nonlinear process such as flash-triggering action potential propagation through thin peripheral layer of cell cytoplasm of Noctiluca scintillans . The equation derived imposes an additional constraint on Noctiluca scintillans flash model parameters enabling one to exclude one of the six optimization parameters while flash curve approximation by theoretical model. Analysis allows us to conclude dependence of exponential decay rate of photoemission on cell physiological state, that is for the same Noctiluca scintillans cell one can register flashes with different bioluminescence decay. Such a conclusion is confirmed by prior studies.</p>
